H205

Basic enthalpy controller used with Honeywell legacy systems

H705

The H705 Solid State Enthalpy Controller maximizes the use of free outdoor air in place of the first stage of cooling in heating, ventilating and air conditioning (HVAC) economizer systems.

HC-101 Series, HC-201

These controllers provide low or line voltage on-off single stage control of humidifiers, dehumidifiers, valves, solenoid valves, compressors, relays, etc.

W42AA Type

The W42AA humidistat provides single pole, double-throw control for use on low or line voltage applications.

The humidistat’s terminals are marked for easy wiring. The “C” terminal is common. The circuit between “C” and “L” terminals closes on a decrease in relative humidity.

W43A

The W43A Humidistat provides SPDT control for use on low or line voltage applications. It has a thermoplastic cover with Allen-head locking screw to discourage unauthorized tampering. The sensing element consists of carefully selected and processed human hair.
